Specification of Letters Patent. Patented Oct. 31, 1911.

Application filed October 5, 1910. Serial No. 585,496.

1 shown each bearer consists-of a plate (Fig. 7) forming the bearerproper marked 3, having on its forward edge, that is the edge Erie, inthe county of Erie and State of toward the platen, a flange 3 whichforms Pennsylvania, have invented certain new the bearing surfacefor'the so-called sockets and useful Improvements in Printing- 3 orcollars of the inking rollers hereinafter Presses, of which thefollowing is a specifiparticularly referred to. Each bearer platecation. has a pin and slot connection with the-side My invention relatesto printing presses of the type bed the same comprising the and theobject thereof is to provide an adslots 3* and the pins or studs 4. Thebearer justable bearer associated with the type bed plate is alsoprovided along its length with of the printing press and arranged to betwo sets of flanges 53 and 3 with which coadjusta-ble inwardly andoutwardly with operate the second or operating plate 5, respect to theface of the type bed or frame, shown by itself in Fig. 8. This secondplate such bearer beihg the part of-the press on also has a pin and slotconnection with the which the collars or so-called sockets of the typebed through the medium of its slots 5 inking rollers travel or-bear. andthe same studs or pins 4 that cooperate In the drawings Figure'l is aside elevawith the bearer plate proper. The forward tion of 21 Gordontype of press in connecedge of this second plate has a series of racktion with which I have chosen to illustrate teeth 5 formed adjacent theopening 3 in my invention; Fig. 2 a side elevation of one the bearerplate. This rack and said openside of the type bed illustrating myadjusting are so formed as to receive the so-called able bearer inposition; Fig. 3 a central quoin key used by printers in locking uplongitudinal section on the line 3-3 of Fig. their chase, the same toolinstead of a 2; Figs. 4 and 5 cross sections on the lines special toolbeing used for sake of con- 4-4 and 55 respectively of Fig.2; Fig.venienee. 6-a section on the line 66 of Fig. 4; Fig. 7 The parts beingassembled as illustrated an elevation of the bearer proper; and Fig. inFig. 2 for instance and it being desired 8 an elevation of the operatingplate assoto adjust the bearer plate the studs or screws ciated with thebearer plate. 4 are loosened and the quoin key inserted in In thepresent instance I have illustrated the opening 3 and turned in theproper dimy invention in connection with a Gordo rection accordingly asit is desired to adjust type of printing press whichI have provided thebearer inwardly or outwardly. Through with my" feeding attachment suchas is the operating engagement between the two plates through the mediumof the flanges the bearer plate is caused to move inwardly or outwardlyaccordingly as the operating plate is moved up or down by the key. henthe bearer plate has been moved or adjusted to the proper position thestuds or screws are tightened. Inorder to provide for an. accurateadjustment of the bearer and the same adjustment onboth sides, I providethese plates with graduations which are indicated in Fig. 2 at 6. Ashereinbefore stated, the so-called sockets of the inking rollers travelupon these bearers. As shown in Figs. 4 and 6 the inking roller 7 isprovided at its ends with collars or sockets 8 bearing upon said bearersand forming treads traveling upon the bearers, there be ing recesses orreduced portions at 8 between the sockets proper and the ends of theirinking roller, these recesses having no bearing whatever upon thebearers. In

Be it known that I, KARL F. KIRKMAN, a citizen of the United States,residing at shown and described in my prior application filed on October1, 1909, Serial No. 520,512. provision of the transfer frame shownherein at a for the purpose of 1 handling the sheets of paper in feedingthe press the usual construction of type bed and the bearers thereofcannot be employed because of interference between such frame and thebearers. For this reason I have have made the same adjustable, but itwill i be understood that my invention is not 1 limited to thisparticular type of press nor to a press provided with my press feeder orany other feeder but is applicable to printing presses in general.

Referring to the present embodiment of my invention the usual type bed 1is provided on its opposite sides and adjacent the platen 9., with thebearer deviceseach of which is similarly made and operated. As

usual form of said sockets but reverse them so as to bring their treadsin position to cooperate with the bearers as clearly illustrated in thedrawings.

Vl hat I claim is:

1. In combination with a type bed of a printing press, bearers thereoneach comprising a pair of plates slidable upon each other but movable indirections at right angles to each other, one of said plates beingmovable toward and away from the plane of the type bed; substantially asdescribed.

2. In combination with a type bed of a printing press, bearers thereoneach comprising a pair of plates slidable upon each other but movable indirections at right angles to each other, one of said plates beingmovable toward and away from the plane of the type bed, the other ofsaid plates having a rack for operating purposes; substantially asdescribed.

In combination with a type bed of a printing press, bearers thereon eachcomprising a pair of plates slidable upon each other and movable indirections at right angles to each other, and having pin and slotconnection with, each other, and means for operating one of the plates;substanl'ially as described.

4%. in combination with a type bed of a printing press, bearers thereoneach comprising a pair of plates slidable upon each other and 'niovablein directions at right angles to each other, one of the plates havingflanges and the other thereof having inclined edges cooperating withsaid flanges; substantially as described.

In combination with the typebcd of a printing press, an adjustablebearer at each side thereof comprising a plate forming the bearer properand having sliding engagement with the bed, and a second platecooperating with the first plate and having sliding engagement with thefirst plate and arranged to .move the latter inwardly and outwardly withrespect to the face of the type bed, said plates being movable indirections at right angles to each other; sub stantially as described.

6. In combination with the type bed of a printing press, an adjustablebearer at each side thereof comprising a plate forming the bearer properand having sliding engage-- ment with the bed, and a second platesliding upon the first plate and longitudinally movable, said secondplate being arranged to operatively engage and thereby move the firstplate, said plates being movable in directions at right angles to eachother; substantially as described.

7. In combination with the type bed of a printing press, an adjustablebearer at each side thereof comprising a plate forming the bearer properand having sliding engagement with the bed, and a second plate slidingupon the first plate and longitudinally movable, said second plate beingarranged to operatively engage and thereby move the first plate, saidsecond plate having a rack to receive an operating tool and the firstplate having an opening to receive the same tool; substantially asdescribed.

8. In combination with the type bed of a printing press, an adjustablebearer at each side thereof comprising a plate forming the bearer properand having sliding engagement with the bed through a pin and slotconnection, and a second plate co6perating with the first plate andarranged to move the latter inwardly and outwardly with respect to theface of the type bed, said second plate having pin and slot connectionwith the bed through the same pin as the first plate; substantially asdescribed.

9. In combination with the type bed of a printing press, an adjustablebearer at each side thereof comprising a plate form ing the bearerproper and having sliding engagement with the bed, said plate havingside flanges, and a second plate coiiperating with said flanges to movethe first plate inwardly and outwardly with respect to the face of thetype bed; substantially as described.
